System.Net.Http.Headers
Specifies the state of the parser flags for HTTP header parsing.
This enumeration is used internally by the .NET framework to manage the parsing state of HTTP headers, particularly in scenarios involving complex or potentially malformed header data.
public enum HttpParserStateParserFlags
No specific parser flags are set. This is the default state.
Indicates that the parser should continue processing on the next header line, even if the current line seems complete or malformed. This can be useful for handling certain legacy or non-standard header formats.
Instructs the parser to skip the next header line encountered. This might be used to ignore specific header fields or lines that are not relevant to the current parsing context.
Signals that the current field being parsed is enclosed in quotation marks. This affects how whitespace and special characters within the field are interpreted.
Indicates that a trailing comma has been encountered, which might be valid in certain header field syntaxes (e.g., comma-separated lists).
Marks that the parser is currently expecting a value for a header field.
Marks that the parser is currently expecting a header name.
The HttpParserStateParserFlags enum is an internal detail of the .NET HTTP client and server implementations. Developers typically do not interact with this enum directly. Its purpose is to provide fine-grained control over the state machine used to parse raw HTTP header data according to RFC specifications and common extensions.
Understanding these flags can be beneficial for debugging complex HTTP communication issues or for implementing custom HTTP parsing logic, though direct manipulation is rarely required.
